11 Claim 12-80) This invention relates to channel cementing A cement-applying roll 10 of disk shape is promachines of the type shown in Letters Patent of vided with a sharpened or wedge-shaped periphthe United States No. 1,778,184, granted October cry 12 comprising opposed faces 13 and 14 which 14, 1930, upon the application of John W. Cosare knurled or roughened slightly to improve grove, the illustrated machine being particularly their cement-carrying capacity. This roll has 5 adapted for operating upon the channels of ruba hub 16 slotted to engage a pin upon a driven ber or composition soles preparatory to laying shaft 18 journaled in a frame 20, the structure of the channel flaps. l which may be substantially or exactly like that In the manufacture of certain styles of shoes, shown in the Cosgrove patent to which reference notably sport shoes, there is used a type of sole has been made. This frame embodies a flat- 10 containing more or less vulcanized rubber which tened horizontal arm 22 to the upper side of is attached to the shoe by stitching, and this which there maybe attached a suitable recepstitching is sometimes done in a channel. The tacle 24 having a delivery opening 26 communichannel flap of such a sole has substantial resileating with a passage 28 in said plate. The flow ience and will not stay back, and the cementing of cement through the delivery opening 26 may 15 of these channels, in order that the flap may be be controlled by a valve 30. The under side of securely attached to the sole, cannot readily be the arm 22 is provided with an undercut groove carried out by the use of machines of the type 32 for the reception of the complemental part of a shown in the above-mentioned patent, where the slide 34 forming one side of a casing surrounding cement is applied by means of a rotary brush, the applying roll 10 and coacting with the inner 20 because of the difliculty in holding the channel side face of the roll. Coacting with the outer flap open and of getting the brush well into the side of the roll 10 is ad wall 36 upon a scraperchannel. carrying arm 38 adjustabLv secured to the slide Accordingly, an important object of the inven- 34 by means of a screw 40 passing through a tion is to provide an improved channel-cementhorizontal slot in said arm 38, thereby enabling 25 ing machine especially adapted for use upon the position of the arm and the wall 36 carried channeled rubber soles and by means of which thereby to be adjusted to correspond with the cement may be evenly applied to all portions of thickness of the roll 10. Carried upon this arm the channel including the inside of the channel 38 is a scraper blade 42 provided with a V-shaped flap. This object is attained by the use of a slot 44. This scraper 42 is attached to the arm 30 cementing machine organization including a ce- 38 by screws 46, and the slot 44 is so designed ment applying device which is formed and adaptthat the scraper lies in close relation to the downed to push apart the channel flap and the body going side of the roll 10 rotated in a counterportion and to apply cement thereto. As illusclockwise direction as viewed from the front of trated, the machine includes a rotary applying the machine. The scraper therefore controls the 5 member of special construction adapted to open quantity of cement taken out of the machine by the channel and to reach all portions thereof. the applying member, while the close relation of As shown, this applying roll has a wedge-shaped the casing formed by the slide 34 and the wall periphery, to both faces of the sharpened portion 36 to the ends of the roll prevents leakage of eeof which cement is supplied in controlled quantiment at these points. Because of the fairly heavy 4o ties. Provision is also made in the illustrated consistency of the rubber cement usually emmachine for holding the channel flap firmly ployed for such work, no special precautions against the applying roll by means of an operagainst leakage need to be taken with respect to ator-controlled presser roll normally spring sephe nil-8 i Of the 11 50 lon as the roll 45 arated from the applying roll. is in motion, and the valve 30 may be closed 45 These and other features of the invention are when the machine is not in use. more fully described in the following speciflca- The machine is illustrated as in use for the tion taken in connection with the accompanying application of cement to the channel and to drawing, in which the flap 52 of a rubber sole 54 to the upper surface Fig. 1 is a side elevation of the working parts of which there is secured a thin leather cover 50 of the machine; 56 which is cemented to the sole and is also se- Fig. 2 is a front elevation of the applying roll cured thereto by 8- r w of i h n 8- The sole and its surrounding casing; and 54 is shown as attached to the insole 60 and the Fig. 3 is a plan view on a larger scale of the upper 62 of a shoe by means of a row of stitching 66 channel flap presser and its support. 64 positioned in a groove 66 formed near the 66 bottom of the channel 50. It is desired that the cement should be applied all the way to the bottom of the channel 50, thereby covering the stitches 64 and making sure of the firm adherence of the channel flap 52. The sole 54 has suflicient rigidity so that.the operator may readily press it against the outer face 13 of the wedge-shaped periphery of the roll 10. The sharpened periphery 12 of this roll facilitates its insertion in the channel 50, pushing aside the channel flap 52 and depositing cement all the way to the bottom of the channel. The shoe may be moved either with or against the direction of rotation of the roll 10 in accordance with the particular work and the desires of the shoemanufacturer. It is not desirable that the surface of the roll 10 shall be unduly rough because of the abrading effect upon the rubber of the sole. 0n the other hand, it should not be absolutely smooth because of the slipperiness" of the cement and the diihculty in obtaining a uniform application of cement with such a roll.

The channel flap 52 is comparatively thin and, although it has a substantial resilience urging it toward the body of the sole 54, it nevertheless does not have sufficient rigidity or strength to insure its flrm contact with the inner side 14 of the wedge-shaped surface of the applying roll across the whole width of the flap. Accordingly, there is provided a presser roll '10 mounted for free rotation at the-end of a lever 72 pivoted upon a screw 74 threaded in an arm 76 adjustably secured to the frame of the machine. A spring '18 surrounding an adjustable stop screw 80 threaded in a flange 82 formed upon the arm 76 controls the relation of the pressure roll to the work and, in the arrangement shown, tends to move the presser roll away from the work and thus avoids any accidental contact of the presser roll with the cement upon the applying roll when no work is being presented. The inner end of the lever '12 is connected by means of a chain 82 with a treadle 84 normally held in elevated position by means of a spring 86. Various adjustments of the position of the presser roll 70 are provided by reason of the mounting of the arm 76. The end of this arm is turned at right angles and held against an angle iron 88 by means of a bolt 90 passing through horizontal slots in these parts. The angle iron 88 is adjustably attached to the frame 20 by means of a thumb screw 92 passing through a horizontal slot in the frame. This arrangement provides for adjustment of the posi tion of the presser roll '10 in two angularly related horizontal directions. The adjustment provided by the bolt 90 in a direction substantially parallel to the line of feed is primarily for the purpose of insuring the correct position of the roll in setting up the machine, while the adjustment provided by the thumb screw 92 in a direction substantially parallel to the axis of the applying roll enables correct positioning of the presser roll toward and away from the face of the applying roll to acommodate channel flaps of different thicknesses.

In the operation of the machine, as the shoe is presented to the machine, the sharpened periphery 12 of the app yin roll enters the channel, pushing aside the channel flap 52, and the shoe is held by the operator so that the channeled sole is in firm contactwith the outer surface 13 of the apply g roll. The shape of the applying roll enables it readily to enter all the way to the bottom of the channel as the shoe is moved horizontally with respect to the lower side of the applying roll in the customary manner. During this. operation the channel flap 52 is pressed against the inner face 14 of the applying roll by means of the presser roll 70, operator-controlled through the use of the treadle 84. The stop screw 80 in the supporting bracket makes it easy for the operator to avoid undue pressure upon the flap.
